UI (Local NEAR Wallet) does not work on localnet when accessed remotely

[andrew-sol]

Problem I followed this guide: https://docs.near.org/docs/tools/kurtosis-localnet But I did the setup on a separate Linux machine that is connected to my local network.

The problem is that the UI opens in my browser when I access it via http://192.168.88.112:49162 but it sends all requests to http://127.0.0.1:49159. Look at the screenshot.

Expected Behavior Domain IP address is not hardcoded and all the request URLs are relative to the current domain.

Well, the issue exists in other UI tools as well (Explorer).

If someone is interested, I overcame the issue by using a simple NodeJS script for forwarding a bunch of ports used by Kurtosis (the ports might be different for each user).

mkdir near-port-forward && cd near-port-forward
yarn add http-proxy
touch main.js

main.js:

const httpProxy = require("http-proxy");

const ports = [];

for (let port = 49158; port <= 49162; port++) {
  ports.push(port);
}

// forward the ports
ports.forEach((port) => {
  console.log(`Forwarding port: ${port}`);

  httpProxy
    .createProxyServer({ target: { host: "192.168.88.112", port }, ws: true })
    .listen(port);
});

Run:

node main.js

The script has to be run from the local machine.

Alternatively, you could update the config on near-cli directly https://github.com/near/near-cli/blob/47e656177135b27e738c593c6e6960dbdfc7ad2d/config.js#L68
